Description

Technical Field

[0001] The utility model relates to the field of top cutting pliers, in particular to a pair of injection molded rib top cutting pliers with controllable shearing depth. Background Art

[0002] In the injection molded parts of automobile exteriors, the ribs of the injection molded parts are often slightly longer or higher, which will directly affect the welding quality of the ribs during ultrasonic welding and the assembly gap of the parts. To solve the problem of the ribs of the injection molded parts being slightly longer or higher, one way is to shorten the depth of the rib holes in the mold, and the other is to manually cut the ribs that are too long or too high to meet the requirements.

[0003] Disadvantages of existing technology:

[0004] The first method of modifying the depth of the rib hole of the mold has the following disadvantages: the depth of a small distance is difficult to control. Even if the depth requirement is met, the material filled in the rib depth on the mold will fall off due to the continuous ejection of the mold and finally return to the original state;

[0005] The second disadvantage of manual cutting is that it is impossible to effectively control the length or height of the tendon slices to be consistent each time they are cut.

[0006] Therefore, it is necessary to provide an injection molded part rib top cutting pliers with controllable shearing depth to solve the above technical problems. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides an injection molded part rib top cutting pliers with controllable shearing depth.

[0008] The utility model provides an injection molded part rib sheet top cutting pliers with controllable shearing depth, comprising a left pliers body and a right pliers body, the left pliers body and the right pliers body being hinged by a riveted shaft, the ends of the left pliers body and the right pliers body being provided with pliers blades that cooperate with each other, a shearing notch being formed between the two pliers blades, the riveted shaft being provided with a mounting seat, a square portion, a circular portion and a pier head in sequence from bottom to top, the left pliers body being provided with a circular hole that cooperates with the circular portion, the right pliers body being provided with a square hole that cooperates with the square portion, an L-shaped slide plate being slidably connected in the mounting seat, a blocking portion being provided at one end of the L-shaped slide plate, and the blocking portion being arranged opposite to the shearing notch, and a driving component for controlling the L-shaped slide plate to slide along the mounting seat being installed on the mounting seat.

[0009] Preferably, a square slide is provided in the mounting seat, one end of the L-shaped slide is slidably connected in the square slide, a connecting plate is fixed on one side of the mounting seat facing the square slide, a threaded hole is provided at one end of the L-shaped slide located in the square slide, a threaded rod is threadedly connected in the threaded hole, one end of the threaded rod passes through the connecting plate and is exposed to the outside of the mounting seat, and the threaded rod is rotatably connected to the connecting plate.

[0010] Preferably, an adjusting nut is fixed to one end of the threaded rod.

[0011] Preferably, the side wall of the threaded rod is provided with annular scale lines.

[0012] Preferably, a V-shaped spring piece is installed between the left clamp body and the right clamp body.

[0013] Compared with the related art, the utility model provides the following beneficial effects: through the design of the L-shaped slide plate and the blocking part, and the precise adjustment mechanism of the threaded rod and the threaded hole, the shear depth can be very finely controlled. This design is extremely beneficial for the processing of injection molded ribs that require high-precision shearing operations. The setting of the adjustment nut and the annular scale line greatly simplifies the operation process. The operator can intuitively read and adjust the shear depth quickly through the annular scale line, which improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figures 1 to 6, an injection molded part rib top cutting pliers with controllable shearing depth, composed of a left pliers body 1 and a right pliers body 2, which are flexibly hinged together through a riveted shaft 3. A pair of mutually engaged pliers blades 4 are arranged at the tips of the left pliers body 1 and the right pliers body 2, forming a precise shearing opening 5 between them. When the rib of the injection molded part is placed in the shearing opening 5, the rib can be accurately cut off through the close fit and extrusion of the pliers blades 4.

[0023] The structure of the riveting shaft 3 includes a mounting seat 6, a square portion 7, a circular portion 8 and a pier head 9 from bottom to top. In order to ensure the stability and operational flexibility of the top cutting pliers, a circular hole 10 matching the circular portion 8 is provided in the left pliers body 1, and a square hole 11 matching the square portion 7 is provided in the right pliers body 2. The close fit between the square portion 7 and the square hole 11 ensures a stable connection between the right pliers body 2 and the riveting shaft 3.

[0024] In the mounting seat 6, there is an L-shaped slide plate 12 that can slide freely. One end of the L-shaped slide plate 12 is provided with a blocking portion 13, and the blocking portion 13 is directly opposite to the shearing opening 5. By accurately adjusting the distance between the blocking portion 13 and the shearing opening 5, the shearing depth can be finely adjusted. In order to achieve this, the mounting seat 6 is also specially equipped with a driving assembly 14, which can accurately control the sliding of the L-shaped slide plate 12 in the mounting seat 6.

[0025] In order to more finely adjust the L-shaped slide 12, a square slide 15 is specially provided in the mounting seat 6, and one end of the L-shaped slide 12 slides flexibly in this slide. At the same time, a connecting plate 16 is fixed on one side of the mounting seat 6, facing the position of the square slide 15. A threaded hole 17 is provided at the end of the L-shaped slide 12 in the square slide 15, and this threaded hole 17 is tightly threadedly connected to a threaded rod 18. One end of this threaded rod 18 passes through the connecting plate 16 and is exposed to the outside of the mounting seat 6. At the same time, it can rotate freely between the connecting plate 16. By rotating this threaded rod 18, we can accurately drive the L-shaped slide 12 to slide in the square slide 15, so as to finely adjust the shear depth.

[0026] For easy operation, an adjusting nut 19 is fixed to one end of the threaded rod 18, so that we can easily rotate the threaded rod 18 with a wrench. It is worth mentioning that an annular scale line 20 is engraved on the side wall of the threaded rod 18, which enables us to quickly read the precise distance between the blocking portion 13 and the shearing opening 5, thereby more conveniently adjusting the shearing depth.

[0027] In addition, in order to ensure that the top cutting pliers can be easily reset after use, a V-shaped spring 21 is cleverly installed between the left pliers body 1 and the right pliers body 2. In this way, whenever we release our hands, the pliers body can quickly return to its initial state, fully preparing for the next cutting operation.

[0028] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
